Hi, I'm trying to use spring-configuration processor in a library. It does not work. The setup is gradle 5.5.1, kotlin 1.4.50, Spring Boot 2.0.0.M5
To not hog the channel I moved the question to :stackoverflow:
<https://stackoverflow.com/questions/57769464/>

<https://github.com/spring-projects/spring-boot/issues/17560>, did you see it?

yes, but that does not seem to be my case, as I've stated in the question, same setup works for my standalone application

I saw that. did you anyway try with `lateinit var` instead of `val`? as officially `val` is not supported, it might be you hit a corner case when it actually worked

Yes, I tried with `lateinit var`, it didn't work either. But I have narrowed the problem down to IntelliJ.
kapt seems to be doing its job properly: I see that kapt does generate metadata json in `build/tmp/kapt3/classes/main/META-INF` with all my properties inside.
I'll look through intellij tracker and file the issue if there isn't one already.

As you can see in <https://kotlinlang.org/docs/reference/kapt.html>
&gt; note that kapt is still not supported for IntelliJ IDEA’s own build system

So you need to generate metadata via Gradle or Maven

And i think at some point you had to enable annotation processing explicitly in IDEA option but I can"t find the option so this is maybe automatic in latest version

I think it is supported for `val`, but default values are not since we have no way to get them

More globally on that topic, my feeling is that `kapt` is crap and will be replaced by compiler plugins in the future, with full support for any `@ConfigurationProperties` feature, but it is too early since compiler plugin APIs are not stable and unless you are Google or Jetbrains, almost impossible to maintain.

I hope that we will be able to move forward on that next year.

For now I will do a last pass on documentation before Boot 2.2 release, feel free to submit PRs if there are missing warnings or doc.

Sure, I'll do that. Thanks for the comment.
